I have read many complaints regarding high CPU usage in Teams for linux but everytime the team member says "we can't replicate the same at our end".
Today I am posting my screenshots for high CPU usage.
1. CPU usage without teams running.
2. CPU usage with teams running.
No other apps were running in background.
OS : Kubuntu 20.04 LTS
CPU : Intel core i5-8250U
First of all this time as well I am expecting something like "We can't replicate the high usage scenario on our end".
And secondly, there is no roadmap for Teams Linux, so no bugs gets fixed, no new features coming, even the basic feature of Teams which are present in windows version isn't present in Linux version and there is no timeline as to when we'll get those features.

I can always reproduce high cpu usage after any video call. I believe this has been discussed before in other discussions. So basically my workflow is exit and restart teams after every meeting.
Teams for Linux seems to have been released and abandoned.

@pankaj_scanit Got this on my machine too. Running strace on the offending process and found that it was checking whether my laptop was on AC power or not 1100+ times per second. Obviously, if I wasn't on AC power, I would have to be with this kind of code.

Facing the same issue here on Thinkpad T49s and Debian linux.
Checking CPU usage with "top", it shows heavy load on
31962 root 20 0 0 0 0 I 77,8 0,0 0:16.36 kworker/0:2-kacpi_notify
Sounds like it's checking AC power on my machine as well. But I'm most of the time connected with power supply.
That way I'm not able to join a team meeting without power supply ...

There are a few Uservoice items regarding CPU usage and Linux, but they're not being voted for. Perhaps you all can help increase the vote count. Here's an example, but you can search for others: High CPU on Linux when Teams is idle – Welcome to UserVoice!

@pankaj_scanit agreed! Here's my performance graph on a call with four people this morning, with nothing else running, not long after starting the computer up:
For reference, it's a Lenovo Thinkpad with OEM Ubuntu 20.04, Core i7-10510u with 16GB RAM. Was absolutely unusable during the call and it was taking 10-15 seconds for hovering to reveal the mute button.
